Samsung Electronics Co said on Tuesday its Galaxy Gear has become the world's most popular smartwatch with sales reaching 800,000 since its debut two months ago, defying some market concerns the accessory would fail due to a lack of compelling features.

The South Korean firm said Gear sales have been better than its own expectations and it would expand sales promotions for the wearable device for the crucial year-end holiday sales.

Impressive for a poorly reviewed device. I guess this is what marketing and bundling can do - then again, without bundling, flagship smartphone sales would crumble like three week old bread too.
